Marquez stamps his authority on 2015 MotoGPâ„¢ season with impressive win in Austin

The reigning MotoGPâ„¢ World Champion Marc Marquez sent a message out to the rest of the paddock that he was back after his mishap in Qatar, as he dominated the Red Bull Grand Prix of The Americas, at one point leading by over 5 seconds.

After mixed weather over the course of the weekend, the sun came out and track temperatures rose to 35 degrees in time for the start of the MotoGPâ„¢ race.

Andrea Dovizioso led the field into turn 1, with Marquez happy to let the Ducati GP15 open up a 0.5s lead during the opening couple of laps. The Spaniard took the lead on lap 5, and didn’t look back as he went on to leave the rest of the field behind to maintain his 100% record at CoTA, before relaxing towards the end of the race.

A brilliant battle for second then ensued between the Italians Valentino Rossi, Dovizioso, and his Ducati teammate Andrea Iannone. “The Doctor” having to use all of his skill and experience to hold off the charge of the red machines as they tried to make their power advantage count. He would eventually lose out to Dovizioso, who made it another podium for the resurgent Ducati Team, although “The Doctor” maintains his lead in the Championship standings as he finished 3rd.

Rossi's teammate Jorge Lorenzo left it late, overtaking the Ducati GP15 of Andrea Iannone with only 3 laps to go to snatch 4th place from the Italian, with Monster Tech 3 Yamaha's Bradley Smith rounding out the top 6 as the leading Satellite rider.

CWM LCR Honda's Cal Crutchlow recovered from a poor start that saw him down in 10th on the opening lap to finish in 7th, 6 seconds behind Smith.

Aleix Espargaro was a further 2 seconds back in 8th, as he finished 19 seconds ahead of his rookie teammate Maverick Viñales on the second Team Suzuki Ecstar GSX-RR in 9th.

Pramac Racing's Danilo Petrucci completed the top ten, ahead of the Repsol Honda of Hiroshi Aoyama and the leading Open class bike of Hector Barbera on the Avintia Ducati.

Scott Redding earlier crashed at turn 11 taking out Pol Espargaro in the process, much to the chagrin of the Spanish rider, with a number of others also having to retire throughout the race.

Lowes claims heroic maiden Moto2â„¢ win for the UK

Speed Up Racing's Sam Lowes claimed his first ever Moto2â„¢ victory at the Red Bull Grand Prix of The Americas.

It was an incredible Moto2â„¢ race, with moments of drama throughout and a thrilling finish as a number of riders were in with a chance for the race win. Tito Rabat got the best start, leading the field into the first corner, but that would be as good as it got for the Spaniard. Johann Zarco took the lead on lap 1, and he and Lowes then started to gap the rest of the pack. Xavier Simeon and Alex Rins then set about hunting the front two down, catching them with 11 laps still to go.

British rider Lowes bided his time throughout the race, overtaking Ajo Motorsport's Johann Zarco to lead with just 6 laps remaining. As Zarco and Xavier Simeon tried to reel him back in, they made contact, with the latter crashing out in an incident that was investigated by Race Direction but neither rider was found to be at fault.

This left Lowes to take the win, despite having to ride through the pain barrier after a number of huge crashes in Practice and Qualifying. Zarco regained his composure to finish in 2nd, ahead of the rookie Alex Rins on the Paginas Amarillas HP40 Kalex, who now leads the World Championship standings.

The reigning Moto2â„¢ Champion Tito Rabat finished in 4th on the Estrella Galicia 0,0 Marc VDS Racing machine, ahead of the Italtrans Racing Team Kalex of Franco Morbidelli and Hafizh Syarin, who claimed a fantastic 6th place for his Petronas Raceline Malaysia Team.

Imperious Kent takes #AmericasGP Moto3â„¢ win

Danny Kent took his first win of the 2015 Moto3â„¢ season, and 3rd in his career, as he left the rest of the field for dead in Austin.

A drying track led to an incident packed Moto3â„¢ race, as Leopard Racing's Danny Kent went on to take a faultless win at the Circuit of The Americas. The British rider, who was over half a second quicker than the rest of the field in Qualifying, got swallowed up by the pack at the start and dropped back to 5th.

He then set about making his way to the front, taking the lead on the 4th lap, before breaking away unchallenged for the rest of the race to win by over 8.5 seconds. It is unusual to see one rider dominate in a Moto3â„¢ race, but no one had a response to the lap times that Kent was putting in, and for the rest of the riders it became a fight for the remaining spots on the podium.

15-year-old Frenchman Fabio Quartararo (+8.532s) on the Estrella Galicia 0,0 Honda own the battle for second place as Alexis Masbou crashed out on the last corner. Kent's teammate Efren Vazquez took 3rd ahead of the Gresini Racing Team Moto3 bike of Enea Bastianini, with Honda securing a lock out of the top 4 places.

Red Bull KTM Ajo's Brad Binder finished in 5th, with Scotsman John McPhee on the SAXOPRINT RTG Honda rounding out the top 6, after starting from 15th.

A number of riders crashed as they appeared to be caught out by track conditions, with Bagnaia, Loi, Oliveira, Ono, Antonelli and Navarro amongst those hitting the deck.
